Combobox bug

[Guest]

Hi all,

i have found something odd...when a combobox is not selecting the first value (or ComboBox1.SelectedIndex > 0) and your code executes

ComboBox1.SelectedIndex = -1

it will select the first the value (.SelectedIndex=0) instead of deselecting all values. if you want to make the combobox deselect the first value, you must execute the same line of code again.

maybe i'm missing something, any thoughts?

Thanks in advance,

Kunkel

I can also add...
my solution was to do a "ComboBox1.SelectedIndex = -1" twice

but pay attention
if you have a selectedIndex or selectedItem listener

for a selectedindex of for example 2 you will receive following events while
doing the =-1 twice
selectedindex -> -1
selectedindex -> 0
selectedindex -> -1
